Combined Automated Annotation using Multiple IEA Methods
Heterogeneity of the mitochondrial proteome for photosynthetic and non-photosynthetic Arabidopsis metabolism.
Divalent metal ions in plant mitochondria and their role in interactions with proteins and oxidative stress-induced damage to respiratory function.
-
The metal-affinity screen suggests association, but target-specific direct binding remains unresolved.
"The interaction of metal ions with mitochondrial proteins that might be responsible for these toxic effects was investigated in vitro using IMAC to trap metal-binding proteins."
Overexpression of arginase in Arabidopsis thaliana influences defence responses against Botrytis cinerea.
-
A direct role of ARGAH2 in proline metabolism is unresolved.
"Overexpression of
arginase resulted in changes in amino acid accumulation, while polyamine levels
remained largely unaffected."
A proteomic strategy for global analysis of plant protein complexes.
Dual functioning of plant arginases provides a third route for putrescine synthesis.
-
ARGAH also catalyzes agmatine hydrolysis to putrescine.
"Transformation of Arabidopsis thaliana ADC2, and any of the arginases from A.
thaliana (ARGAH1, or ARGHA2) or the soybean gene Glyma.03g028000 (GmARGAH) into
a yeast strain deficient in ODC, fully complemented the mutant phenotype."
Global Analysis of Membrane-associated Protein Oligomerization Using Protein Correlation Profiling.
Phosphatidic acid binds to and stimulates the activity of ARGAH2 from Arabidopsis.
Ornithine-delta-aminotransferase is essential for arginine catabolism but not for proline biosynthesis.
-
Arginase supplies the arginine-cleavage arm of ornithine/arginine recycling.
"Accumulation of Cit indicated that Orn and Arg were metabolised after uptake, most likely by enzymes of the urea cycle."
UniProt record for ARGAH2
Source-specific Arabidopsis localization audit
Arginase-negative mutants of Arabidopsis exhibit increased nitric oxide signaling in root development.
Reproducible Figure 2 localization evidence for Arabidopsis ARGAH1 and ARGAH2
-
Both tagged Arabidopsis arginases localize to the mitochondrial interior in tobacco BY-2 cells, supported by marker colocalization and selective permeabilization.
"Therefore, each protein was actually localized in the mitochondrial interior (matrix)"
